Osmolarity=osmole  of  the  solute/litres  of  the  solution
ionic  equation  for  dissociation  of  CaCl2  is
CaCl2--->Ca2+   +2Cl-
total osmoles  for  reaction are    1(Ca2+)  + 2(Cl-)= 3 osmoles
therefore
 
0.50 moles of  CaCl2  x 3 osmoles/ 1mole of  CaCl2 = 1.5osmoles
osmolarity=1.5 /1.0  L=1.5 osmol/l

Anna71 [15]

Answer:

B. Aromatic

Explanation:

Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.

For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.

Assuming an electron is a hydrogen atom can undergo any of the transitions below, thus changing its energy. Which transition is
inn [45]

Answer:

n = 3 to n = 5

Explanation:

According to the Bohr's model of the atom, electrons in an atom absorb energy to move from a lower to higher energy level.

We must note that as we progress away from the nucleus, the energy levels of electrons become closer together. The energy difference between successive levels decreases and the wavelength of light associated with such transitions become longer.

Hence,the absorption of light of the longest wavelength corresponds to n = 3 to n = 5
